Applications of 70 Ferrosilicon Alloy
1. Steelmaking
The primary application of FeSi 70 is as a deoxidizer and alloying agent in steel production. Incorporating ferrosilicon:
Improves tensile strength, hardness, and ductility of steel
Enhances corrosion resistance in carbon and alloy steels
Reduces oxygen content, minimizing blowholes and cracks in casting
Facilitates the production of stainless steel, structural steel, and specialty alloys
High-quality FeSi 70 ensures uniform steel composition and consistent mechanical properties, critical for modern industrial and construction requirements.
2. Ferroalloy Production
70 ferrosilicon is also a key raw material for producing ferrosilicon alloys, contributing to stable chemical composition and superior performance in metallurgical applications.
3. Chemical and Foundry Industries
FeSi 70 is used in the production of silicon-based chemicals, including silicones and silicates. It is also employed in foundry applications for deoxidation and improving metal fluidity, ensuring high-quality castings.
4. Other Industrial Uses
70 ferrosilicon alloy is applied in specialty alloys, powder metallurgy, and high-temperature industrial processes, where consistent silicon content and chemical stability are critical.
